• 11 SITE STUDY Windy Hill Farm Orange County, North Carolina The site under study is located on the eastern side of University Station Road, (SR 1712), approximatly 1 mile south of the intersection of University Station Road and 1-85. The property covers 80.33 acres. The proposed use of this site is to develop it into a subdivision consisting of 23 lots with a minimum lot size of 1.0 acres. Two roads are proposed to service the site, (Windy Hill and High 1eadow) which will be constructed as cul-de-sacs. There are two _ existing ponds in the center of the site which cover approximately four (4) acres. There are also plans to build a one and one-half, (1 1/2) acre pond at the bottom of -the site. When designing a site within a water supply watershed of regional importance, stormwater runoff from impervious surfaces' must be routed to provide as much natural cleansing as possible- prior to it discharging into a creek or stream. Stormwater runoff from impervious surfaces generally carry large amounts of oil, nutrients, metals, and other pollutants. Generally it is the first one-half (1/2) inch of runoff that carries the highest level of pollutant's. These pollutants can generally be filtered out of the runoff II by on-site infiltration through vegetated areas, retention ponds or by detention structures. The natural terrain of this site combined with the routing of stnrnwater with swales to the pondsland vegetation will provide a naximun utilization of these natural processes. A lower ratio of impervious material to the vegetation of the site would result in lower pollutants associated with a site. The low density associated with this site allows it to have a relatively small amount of impervious surface. . The impervious surfaces associated with this site are as follows: 1.50 +/- Acres Paved Roads .86 +/- Acres Driveways (150' X 12' avg.) 1.40 +/- Acres Dwellings (3.000 SF avg.) 3.76 +/- Acres Impervious Surface Windy }sill Farn 12/1;2/85 l-'aye 1
